Sqlite date time, getting the latest date
0
I have a project about a clinic. I have a table in my database that is about the consultation of the patients. My field's are patientid and consultaion_date. So the example inputs is like this:
PatientID|consultation_date
1 | January/3/2001
1 | December/2/2001
1 | December/6/2003
1 | January/2/2005
2 | January/3/2005
2 | January/31/2005
2 | April/5/2005
Can I have a query statement that's going to give me the patientID and the latest date of the consultation of the patients?
PatientID|consultation_date
1 | January/2/2005
2 | April/5/2005
sqlite date

Are you literally representing dates in the database with strings in the format shown in the question?

Not with that date format, no, since, say, December sorts before June.
